Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example 1

[0033] See also Figure 1-Figure 5 , the utility model provides the following technical solutions:

[0034] Noise reduction device for construction engineering, including:

[0035] Isolation board 1;

[0036] A chute 3, which is provided at the upper end of the isolation plate 1;

[0037] An inner sound insulation board 6, the inner sound insulation board 6 is slidably connected inside the isolation board 1;

[0038] A slider 9, the slider 9 is fixedly connected to the upper end of the inner sound insulation board 6, and the slider 9 is slidably connected in the slide groove 3;

[0039] Two sound insulation cottons 7, the two sound insulation cottons 7 are respectively fixedly connected to the inner walls of the two sides of the isolation plate 1 at the near ends, and the two sound insulation cottons 7 are both in contact with the inner sound insulation board 6;

[0040] A groove 11, which is formed at one side of the isolation plate 1;

[0041] A connecting rod 12, the connecting rod 12 is fixedly connected to the inner walls of both sides of the groove 11 at the near end;

[0042] The hollow handle 13 is sleeved on the circumferential surface of the connecting rod 12 .

[0043] In a specific embodiment of the present utility model, the inner sound insulation board 6 and the slider 9 in the device are provided with two sets of symmetrical designs. The isolation board 1 has a certain sound insulation performance as the basic frame of the device. The inner sound insulation board 6 can be pulled outward, and its size is slightly smaller than the internal space of the isolation board 1, and it can slide left and right inside it. When the inner sound insulation board 6 moves, the slider 9 slides in the slide groove 3 to limit the inner sound insulation board 6, and can also facilitate smooth sliding to ensure the overall stability of the structure. When the inner sound insulation board 6 is pulled out, the sound insulation cotton 7 is made into two pieces, which are respectively installed on the inner walls of both sides of the isolation board 1 near the top. The position is tightly fitted with the inner sound insulation board 6 to further enhance the sound insulation effect. A groove 11 is opened at one end of the isolation board 1 to provide space for the installation of a connecting rod 12. The connecting rod 12 supports the use of a hollow handle 13. The hollow handle 13 is a hidden design. After the hollow handle 13 is buckled out, the inner sound insulation board 6 can be driven to move by pulling the hollow handle 13. It can not only effectively isolate the noise generated at the construction site, but also has the characteristics of flexible adjustment and easy operation. It is suitable for construction environments of different sizes and types, and is helpful to improve the sound environment quality in the construction area and its surroundings.

[0044] For details, please refer to Figure 1-Figure 5 A hollow groove 10 is provided at the upper end of the inner sound insulation board 6 , and a plurality of triangular sound insulation cotton boards 8 are provided in the hollow groove 10 .

[0045] In this embodiment, the triangular sound insulation cotton board 8 is installed in the hollow groove 10, which can reduce the weight of the inner sound insulation board 6 and enhance the sound insulation effect, making it more effective to use.

[0046] For details, please refer to Figure 1-Figure 5The triangular sound insulation cotton boards 8 are designed in groups of two, and the spacing between each group of triangular sound insulation cotton boards 8 is 1 cm.

[0047] In this embodiment: the triangular sound insulation cotton boards 8 are grouped into two, and the interference and attenuation effects of sound waves are optimized through the interaction of the two boards, which is particularly effective when dealing with noise in a specific frequency range. The spacing between them is carefully set at 1 cm. The appropriate spacing can promote multiple reflections and absorption of sound waves between the sound insulation cotton boards, further reducing the sound energy passing through the sound insulation structure, while avoiding the sound wave "diffraction" effect caused by too small a spacing or the weakened sound insulation continuity due to too large a spacing.

[0048] For details, please refer to Figure 1-Figure 5 , both side ends of the isolation plate 1 are fixedly connected with a soft pad 2, and the material of the soft pad 2 is silicone.

[0049] In this embodiment, the soft pad 2 is made of silicone material, which has good elasticity, weather resistance and shock absorption performance, and can absorb slight vibrations that may occur during the construction process and reduce structural resonance.

[0050] For details, please refer to Figure 1-Figure 5 A circular rod 5 is fixedly connected to the adjacent ends of the upper and lower inner walls of the isolation plate 1, and the hollow groove 10 is in contact with the inner sound insulation plate 6.

[0051] In this embodiment, the round rod 5 can prevent the two inner sound insulation boards 6 from colliding with each other, keep them tight and seamless, and avoid the generation of air leakage.

[0052] For details, please refer to Figure 1-Figure 5 A clamping plate 4 is provided at the upper end of the isolation plate 1 , and the clamping plate 4 is located in the slide groove 3 .

[0053] In this embodiment: the clamping plate 4 provides a fixing point for the inner sound insulation board 6 to prevent the inner sound insulation board 6 from automatically moving and is used for limiting the position.

[0054] The working principle and use process of the utility model are as follows: the inner sound insulation board 6 can be pulled outward by toggling the hollow handle 13. When pulling, the sliding connection mechanism of the slider 9 in the slide groove 3 pulls the inner sound insulation board 6 out to the outside of the isolation board 1, and the two sound insulation cottons 7 are respectively installed and fixed on the close ends of the inner walls on both sides of the isolation board 1 to ensure that they are tightly fitted with the inner sound insulation board 6. It can not only effectively isolate the noise generated at the construction site, but also has the characteristics of flexible adjustment and easy operation. It is suitable for construction environments of different sizes and types, and helps to improve the sound environment quality in the construction area and its surroundings.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
